[PATCH v2 00/12] MediaTek dt-bindings sanitization (MT8173)

[PATCH v2 00/12] MediaTek dt-bindings sanitization (MT8173)

[Ariel D'Alessandro]

This patch series continues the effort to address Device Tree validation
warnings for MediaTek platforms, with a focus on MT8173. It follows the
initial cleanup series by Angelo [0].

Similarly to the ongoing MT8183 work done by Julien Massot, this patchset
eliminates several of the remaining warnings by improving or converting DT
bindings to YAML, adding missing properties, and updating device tree files
accordingly.

[0] https://www.spinics.net/lists/kernel/msg5780177.html

Changes in v2:
* Wrapped commit messages to 75 columns line wrap.
* Replaced "YAML" by "DT schema" in patches subject and content.
* mt8173-mdp: Fixed properties: compatible, clocks, iommus and
  mediatek,vpu.
* mt8173-vpu: Fixed line wrap. Dropped memory-region property description.
* mediatek,mmsys: Dropped patch as it's not a binding issue.
* mediatek,od: Rewrote commit log with details on DT schema users missing
  the related property. Rewrote mediatek,gce-client-reg property.
* mediatek,ufoe: Rewrote commit log with details on DT schema users missing
  the related property. Rewrote mediatek,gce-client-reg property.
* marvell,sd8897-bt: Moved to net/bluetooth/. Added missing ref to
  bluetooth-controller.yaml. Dropped example. Updated reference in another
  file. Minor fixes in properties.
* mediatek,mt8173-rt5650: Dropped unnecessary quotes and unused label.
* dlg,da9211: Dropped enable-gpios description. Rewrote generic example
  node names. Minor fixes in properties.
* melfas,mip4_ts: Dropped unnecessary quotes. Added "active high" to
  ce-gpios property description.
* mediatek,jpeg: Dropped patch as it doesn't apply.

[PATCH v2 03/12] dt-bindings: net: Convert Marvell 8897/8997 bindings to DT schema

[Ariel D'Alessandro]

Convert the existing text-based DT bindings for Marvell 8897/8997
(sd8897/sd8997) bluetooth devices controller to a DT schema.

While here:

* bindings for "usb1286,204e" (USB interface) are dropped from the DT
  schema definition as these are currently documented in file [0].
* DT binding users are updated to use bluetooth generic name
  recommendation.

-Marvell 8897/8997 (sd8897/sd8997) bluetooth devices (SDIO or USB based)
-------
-The 8997 devices supports multiple interfaces. When used on SDIO interfaces,
-the btmrvl driver is used and when used on USB interface, the btusb driver is
-used.
-
-Required properties:
-
-  - compatible : should be one of the following:
-	* "marvell,sd8897-bt" (for SDIO)
-	* "marvell,sd8997-bt" (for SDIO)
-	* "usb1286,204e"      (for USB)
-
-Optional properties:
-
-  - marvell,cal-data: Calibration data downloaded to the device during
-		      initialization. This is an array of 28 values(u8).
-		      This is only applicable to SDIO devices.
-
-  - marvell,wakeup-pin: It represents wakeup pin number of the bluetooth chip.
-		        firmware will use the pin to wakeup host system (u16).
-  - marvell,wakeup-gap-ms: wakeup gap represents wakeup latency of the host
-		      platform. The value will be configured to firmware. This
-		      is needed to work chip's sleep feature as expected (u16).
-  - interrupt-names: Used only for USB based devices (See below)
-  - interrupts : specifies the interrupt pin number to the cpu. For SDIO, the
-		 driver will use the first interrupt specified in the interrupt
-		 array. For USB based devices, the driver will use the interrupt
-		 named "wakeup" from the interrupt-names and interrupt arrays.
-		 The driver will request an irq based on this interrupt number.
-		 During system suspend, the irq will be enabled so that the
-		 bluetooth chip can wakeup host platform under certain
-		 conditions. During system resume, the irq will be disabled
-		 to make sure unnecessary interrupt is not received.
-
-Example:
-
-IRQ pin 119 is used as system wakeup source interrupt.
-wakeup pin 13 and gap 100ms are configured so that firmware can wakeup host
-using this device side pin and wakeup latency.
-
-Example for SDIO device follows (calibration data is also available in
-below example).

[PATCH v2 05/12] dt-bindings: display: mediatek,od: Add mediatek,gce-client-reg property

[Ariel D'Alessandro]

Currently, users of Mediatek OD (display overdrive) DT bindings set
mediatek,gce-client-reg node property, which is missing from the DT schema.

For example, device tree arch/arm64/boot/dts/mediatek/mt8173.dtsi is
causing the following dtb check error:

```
$ make CHECK_DTBS=y mediatek/mt8173-elm.dtb
   SCHEMA  Documentation/devicetree/bindings/processed-schema.json
   DTC [C] arch/arm64/boot/dts/mediatek/mt8173-elm.dtb
[...]
arch/arm64/boot/dts/mediatek/mt8173-elm.dtb: od@14023000
(mediatek,mt8173-disp-od): 'mediatek,gce-client-reg' does not match
any of the regexes: '^pinctrl-[0-9]+$'
```

This commit adds the missing node property in the DT schema and updates the
example as well.

(mediatek,mt8173-disp-ufoe): 'mediatek,gce-client-reg' does not match
any of the regexes: '^pinctrl-[0-9]+$'
```

This commit adds the missing node property in the DT schema and updates the
example as well.

[PATCH v2 07/12] arm64: dts: mediatek: mt8173: Fix mt8173-pinctrl node names

[Ariel D'Alessandro]

According to the mediatek,mt8173-pinctrl device tree binding schema, the
pinctrl node names should match pattern 'pins$'. Fix this.

[PATCH v2 10/12] arm64: dts: mediatek: mt8173-elm: Drop unused bank supply

[Ariel D'Alessandro]

The mediatek,mt8173-thermal device tree binding schema doesn't allow
regulator supplies like the ones defined in mt8173-elm.dtsi. Drop these as
the associated driver doesn't implement them either.

Currently, the DT bindings for Mediatek PMIC Wrapper is missing the
power-domains property, which is used in the MT8173 E1 evaluation board as
it needs USB power domain.

Why there is no mediatek,mt8173-mdp here? What does this compatible
represent?

> +      - items:

Still suspicious. Device cannot be simulatanously: compatible and not
compatible. This is not a well known cat that has superposition of two
states, whenenver you look the other way.

Maybe the old binding was incorrect, maybe the in-tree DTS is incorrect.
Whichever the reason, this must be investigated and documented, because
by standard rules this is wrong. Each wrong code needs very clear
explanations (and "someone did it" is not a good enough explanation).

You can drop above 4 lines, they are obvious. Your "dtbs_check error"
message already defined that.

> arch/arm64/boot/dts/mediatek/mt8173-elm.dtb: ufoe@1401a000

The warning message should not be wrapped, so this should be two lines.
Maybe entire warning should be in one line, at least that's what I would
do, after dropping "arch/arm64/boot/dts/".

Anyway, no need to resend just for these. Thanks for the update.

My guess is that "mediatek,mt8173-mdp" is meant to serve as a single
entry point for the implementation to bind the driver to. The MDP is
a Data Pipeline and there could be multiple instances of the same
IP block, as seen in the original example.

The datasheet I have doesn't cover the "RDMA" block specifically, so
I can't say whether there is an actual difference between the two RDMA
blocks.

I am speaking about hardware. What piece of hardware it implements and
why sometimes it is RDMA MDP and sometimes it is not RDMA MDP, but only MDP.

.dts files should be separate patches. Please send the bindings patches 
separately per subsystem so subsystem maintainers can apply them. All 
the Mediatek dts changes can be 1 series.

The schema looks good.
